a) 7/6 + 4/16 = 7/6 + 1/4 = 14/12 + 3/12 = 17/12
b) 2/12 + 15/6 = 1/6 + 15/6 = 16/6 = 8/3
c) 5/7 - 2/6 = 5/7 - 1/3 = 15/21 - 7/21 = 8/21
Chúc bạn học tốt.
😁😁😁
4/16=1/4
7/6+1/4=6/24+28/24=34/34=12/17
2/12=1/6
1/6+15/6=6/36+90/36=96/36=24/9
2/6=1/3
5/7-1/3=15/21-7/21=8/21
2279/3127 = 43/59
3337/4473 = 47/63
43/59 = 2709/3717
47/63 = 2962/3717
suy ra 2962/3717 > 2709/3717
3337/4473 > 2279/3127
k mik nha ^^
\(\frac{2279}{3127}\)= \(\frac{43}{59}\)
\(\frac{3337}{4473}\)= \(\frac{43}{59}\) mà \(\frac{43}{59}\)= \(\frac{43}{59}\) =>\(\frac{2279}{3127}\)= \(\frac{3337}{4473}\)
\(\frac{16}{48}=\frac{16:16}{48:16}=\frac{1}{3}\);\(\frac{14}{35}=\frac{14:7}{35:7}=\frac{2}{5}\)
\(\frac{1}{3}=\frac{1\cdot5}{3\cdot5}=\frac{5}{15}\); \(\frac{2}{5}=\frac{2\cdot3}{5\cdot3}=\frac{6}{15}\)
a) \(\dfrac{6}{14}=\dfrac{6:2}{14:2}=\dfrac{3}{7}\)
\(\dfrac{3}{7}< \dfrac{4}{7}\)
b) \(\dfrac{6}{15}=\dfrac{6:3}{15:3}=\dfrac{2}{5}\)
\(\dfrac{3}{5}>\dfrac{2}{5}\)
c) \(\dfrac{10}{18}=\dfrac{10:2}{18:2}=\dfrac{5}{9}\)
\(\dfrac{5}{9}>\dfrac{2}{9}\)
34 / 51 = 34 : 17 / 51 : 17
= 2/3
Vậy 34/51 = 2/3
Chúc bạn học tốt!
16/48=1/3
34/51=2/3
Vì: 2>1 nên: 1/3<2/3
=>16/48<34/51
Vậy:16/48<34/51
16/48=1/3
34/51=2/3
mà 1/3<2/3
nên 16/48<34/51
